Ebenezer - sorry, there has never been an FR base at BHX. As Daza says, FR operated GRO and MJV in addition to DUB, they were flown by DUB based a/c and crew eg DUB-BHX-MJV-BHX-DUB. The reason there was no effect on LTN pax figures was for the reason they operated just the three routes! With this summers hugely increased schedule, it remains to be seen how this will affect LTN but IMHO I don't think a huge amount, pax in the middle (MK/Northampton etc) are well placed for both airports so it will depend on who offers the best price and schedule when deciding where to fly from. As for annual pax figures, well let the race begin, will BHX regain its 5th biggest airport crown?????
